Subaru Legacy Service Manual: Time lag test inspection

NOTE:

When the select lever is shifted while the engine is idling, there will be a certain time elapse or lag before shock is felt. This symptom helps to check the condition of forward clutch and reverse brake.

Perform the test at normal operation CVTF temperature of 60 — 80°C (140 — 176°F).

Be sure to allow one minute or more interval between tests.

Make three measurements and take the average value.

1. Apply the parking brake.

2. Start the engine. Check the idle speed. (A/C OFF)

3. Shift the select lever from “N” to “D” range. Using a stop watch, measure the time elapsed from shifting the lever until the shock is felt.

Time lag standard:

1.5 seconds or less

If “N” > “D” time lag is longer than specified:

Secondary pressure (line pressure) is too low.

Forward clutch worn

Forward clutch piston malfunction

Control valve body malfunction

Learning incomplete

4. In the same manner, measure the time lag when shifting from “N” range to “R” range.

Time lag standard:

1.5 seconds or less

If “N” > “R” time lag is longer than specified:

Secondary pressure (line pressure) is too low.

Reverse brake worn

Reverse brake piston malfunction

Control valve body malfunction

Learning incomplete
